M51 from the deep south

I wasn't sure whether I should post this one or not because it's not my data. I only did the processing. Then I thought "what the heck", people might like to see it.

I swapped some data with a colleague in the US. He got the Tarantula and I got the Whirlpool galaxy. It's always been one of my favourite galaxies and I enjoyed playing with it.

If people think that this isn't an appropriate post for this forum I apologize in advance.

Cheers

Very Nice!!! everybody should look at the larger image to count all the other galaxies in the field of view!!!
Superb image.!!

Steve,

I think there's something really weird happening there.

The image has a flat, dull, pink hue in the arms of the galaxy. And, the centre of the brightest stars also have tended to a magenta ringing effect. Could be too much logarithmic stretching/DDP?

There's some great data there, that's for sure. Perhaps a reprocess is in order?

I have to agree with Humi - not sure what you have done, but there is a very odd finish to this.

Cheers

I'll have another look at it. I agree it does look a bit flat.

Detail's great! The green channel's had some kind of problem though. Looking froward to the repro.

My first reaction was OOooooh AAAaaaah!

Very nice despite a few minor problems.

Apart from the lack of contrast in the galaxy, it oozes detail.

Thanks for the comments guys. This is a quick reprocess and I think it is a significant improvement. I won't go into detail on what I did wrong the first time except to say that I should know better. I'm not sure if I'll get a chance to look at it again for a while because Christmas is starting to intrude. On that subject I hope you all have a merry one.

Cheers

Steve
